Description

Die Erfindung betrifft einen Aufnahmebehälter für Magnetbandkassetten gemäß der Gattung des Anspruches 1.The invention relates to a receptacle for magnetic tape cassettes according to the preamble of claim 1.

Aus der EP-A-163 221 ist ein Aufnahmebehälter für einen Aufzeichnungsträger, beispielsweise einer Magnetbandkassette, bekannt, der ein Gehäuse mit mindestens einem Transportschieber, der gegen Federvorspannung im Gehäuse verriegelt ist, umfaßt. Die Verriegelungsanordnung wird durch eine an der Frontseite des Schiebers befindliche Taste gebildet, die gegen ein Federelement zur Betätigung eines Riegels eindrückbar ist. Das Federelement besteht aus einem elastischen Biegebalken, an dem der Riegel ausgebildet ist. Beim Drücken der Taste wird über eine Schrägfläche der Riegel angehoben und gleichzeitig das als elastischer Biegebalken ausgebildete Federelement durchgebogen. Durch das Anheben des Riegels wird der in der Schließposition befindliche Transportschieber entriegelt und mittels Federkraft in die Entnahmeposition verschoben. Nach dem Loslassen der Taste wird der Riegel über die Vorspannung des elastischen Biegebalkens wieder in die Rastposition gedrückt.From EP-A-163 221 a receptacle for a recording medium, for example a magnetic tape cassette, is known which comprises a housing with at least one transport slide which is locked in the housing against spring bias. The locking arrangement is formed by a button located on the front of the slide, which can be pressed against a spring element for actuating a bolt. The spring element consists of an elastic bending beam on which the latch is formed. When the button is pressed, the latch is raised over an inclined surface and at the same time the spring element, which is designed as an elastic bending beam, is bent. By lifting the latch, the transport slide located in the closed position is unlocked and moved into the removal position by spring force. After releasing the button, the bolt is pressed back into the latching position by the pretension of the elastic bending beam.

Beim Zurückschieben des Schiebers treffen am Riegel angeordnete Schrägflächen auf die Stirnkante der Gehäusebodenwand auf und drücken die Riegel gegen die Federkraft des elastischen Biegebalkens nach oben. Sobald die innere Endlage des Schiebers erreicht ist, überlaufen die Riegel entsprechende Durchbrüche in der Gehäusebodenwand, in die sie aufgrund der Federwirkung des elastischen Biegebalkens einrasten.When the slider is pushed back, bevels arranged on the latch strike the front edge of the housing bottom wall and press the latches upwards against the spring force of the elastic bending beam. As soon as the inner end position of the slide has been reached, the bolts overflow corresponding openings in the housing bottom wall into which they snap due to the spring action of the elastic bending beam.

Diese Lösung ist insofern sehr aufwendig, da sie einen kompletten Riegelkasten mit einer Vorder- und Rückwand zur Führung und Halterung der Taste und des mit dem Riegel versehenen elastischen Biegebalkens erforderlich macht. Des weiteren ist eine Unter- und Oberseite des Riegelkastens zur Abstützung des Biegebalkens und zur Führung des Riegels erforderlich. Damit ergibt sich eine sehr aufwendige Montage der Verriegelungsanordnung, die nicht oder nur sehr schwer automatisierbar ist.This solution is very complex in that it requires a complete bolt box with a front and rear wall for guiding and holding the button and the elastic bending beam provided with the bolt. Furthermore, a bottom and top of the transom box is required to support the bending beam and to guide the transom. This results in a very complex assembly of the locking arrangement, which is difficult or impossible to automate.

Des weiteren besteht bei der bekannten Verriegelungsanordnung die Gefahr, daß diese nicht störungsfrei arbeitet. Da sowohl die Taste als auch der elastische Biegebalken mit Riegel bei der bekannten Ausführung in einem Riegelkasten geführt und gehalten sind, können bei größeren Temperaturschwankungen und häufiger Betätigung Formveränderungen der Kunststoffteile eintreten, die ein exaktes Zusammenwirken der Teile nicht mehr gewährleisten.Furthermore, there is a risk in the known locking arrangement that it does not work without problems. Since both the button and the elastic beam with Bolts are guided and held in a bolt box in the known embodiment, changes in shape of the plastic parts can occur with larger temperature fluctuations and frequent actuation, which no longer guarantee an exact interaction of the parts.

Der Erfindung liegt die Aufgabe zugrunde, für einen Aufnahmebehälter der eingangs genannten Gattung eine einfache kostengünstig herstellbare und montierbare Verriegelungsanordnung zu schaffen, die auch bei ungünstigen Bedingungen eine störungsfreie Funktion gewährleistet.The invention has for its object to provide a simple inexpensive to manufacture and assemble locking arrangement for a receptacle of the type mentioned, which ensures trouble-free operation even under unfavorable conditions.

Die Lösung dieser Aufgabe wird bei einem Aufnahmebehälter der eingangs genannten Gattung durch die im kennzeichnenden Teil des Hauptanspruchs angegebenen Merkmale erhalten. Aufgrund der drehelastischen Lagerung des mit der Taste in Verbindung stehenden Federelements biegt sich dieses bei Betätigen der Taste durch. Das Federelement ist dabei an zwei Punkten fixiert, so daß bei Druck auf die Taste der Riegel aus der Gehäuseöffnung zur seitlichen Begrenzung des Schiebers hin bewegt wird. Hierdurch wird der Schieber aus dem Gehäuse des Aufnahmebehälters entrastet und mittels Federkraft in eine Entnahmeposition ausgeschoben. Die Einführung des Schiebers in das Gehäuse des Aufnahmebehälters ist trotz des an der Verriegelungsanordnung befindlichen Riegels problemlos möglich, da die an diesem befindliche Schrägfläche den Riegel bei Eindringen in das Gehäuse in eine mit der seitlichen Begrenzung des Schiebers abschließende Stellung bringt. Hat der Schieber im Gehäuse des Aufnahmebehälters seine Endposition erreicht, rastet der Riegel in die ihm gegenüberliegende Öffnung der Seitenwand des Gehäuses des Aufnahmebehälters ein und verriegelt somit den Schieber im Aufnahmebehälter.The solution to this problem is obtained in a receptacle of the type mentioned by the features specified in the characterizing part of the main claim. Due to the torsionally elastic mounting of the spring element connected to the key, it bends when the key is pressed. The spring element is fixed at two points so that when the button is pressed, the bolt is moved out of the housing opening to the lateral limitation of the slide. As a result, the slide is unlocked from the housing of the receptacle and pushed out into a removal position by means of spring force. The insertion of the slider into the housing of the receptacle is possible without any problems, despite the bolt located on the locking arrangement, since the inclined surface located there brings the bolt into a position that closes the lateral limitation of the slider when it enters the housing. When the slide in the housing of the receptacle has reached its end position, the latch engages in the opening in the side wall of the housing of the receptacle opposite it and thus locks the slide in the receptacle.

Da Reibungs- oder Kontaktflächen an der Verriegelungsanordnung nicht vorhanden sind, kann auch infolge vielfacher Betätigung der Taste ein Verschleiß an der Verriegelungsanordnung nicht auftreten.Since there are no friction or contact surfaces on the locking arrangement, wear on the locking arrangement cannot occur due to repeated actuation of the button.

Beim Entriegelungsvorgang wird eine Umsetzung des auf die Taste ausgeübten Drucks in eine rechtwinklig dazu stehende Entriegelungsbewegung dadurch erreicht, daß das mit der Taste in Verbindung stehende, aus einem elastischen Biegebalken bestehende Federelement sich durchbiegt. Dabei wird das Herausgleiten des Riegel aus der Gehäuseöffnung des Aufnahmebehälters sowie der formschlüssige Abschluß des Riegels mit der seitlichen Begrenzung des Schiebers dadurch ermöglicht, daß das dem Riegel gegenüberliegende Ende des Biegebalkens am Schieber drehelastisch fixiert ist und im Bereich des Riegels vom Biegebalken ein Kragträger absteht, der an einem weiterem Lageransatz am Schieber fixiert ist. Durch die drehbewegliche Fixierung des Biegebalkens an den beiden Lageransätzen wird somit die Durchbiegung des Biegebalkens ermöglicht, wobei der Riegelfortsatz während des Biegevorgangs eine zur seitlichen Begrenzung des Schiebers gerichtete Schwenkbewegung beschreibt.During the unlocking process, a conversion of the pressure exerted on the key into an unlocking movement at right angles to it is achieved by the fact that the key is connected from one elastic bending beam existing spring element bends. The sliding of the bolt out of the housing opening of the receptacle and the form-fitting closure of the bolt with the lateral limitation of the slide is made possible in that the end of the bending beam opposite the bolt is fixed in a torsionally elastic manner and a cantilever protrudes from the bending beam in the region of the bolt. which is fixed to a further bearing approach on the slide. The rotationally fixed fixing of the bending beam to the two bearing attachments thus enables the bending of the bending beam, the locking extension describing a pivoting movement directed towards the lateral limitation of the slide during the bending process.

Die Übertragung des auf die Taste ausgeübten Drucks auf den Biegebalken wird über einen, die Taste mit dem Biegebalken verbindenden Steg ermöglicht. Dieser trifft am Biegebalken auf den Scheitel eines an diesem ausgebildeten stumpfen Winkels, wodurch der Verlauf des Biegevorgangs vorgegeben ist.The transmission of the pressure exerted on the key to the bending beam is made possible via a web connecting the key to the bending beam. This meets the apex of an obtuse angle formed on the bending beam, whereby the course of the bending process is predetermined.

Die Verriegelungsanordnung kann dabei in der Weise vorgesehen sein, daß die Taste mit dem Biegebalken ein Element bildet, wobei der Biegebalken im Bereich der bei den übrigen Ausführungen ausgebildeten Lageransätze am Schieber angespritzt ist. Ein zusätzlicher Montageaufwand wird hierdurch vermieden. Die Elastizität beim Biegevorgang ist dadurch ermöglicht, daß am zwischen Taste und Biegebalken angeordneten Steg ein im Durchmesser verjüngter Abschnitt vorgesehen ist, der somit für eine weitere elastische Biegemöglichkeit sorgt.The locking arrangement can be provided in such a way that the button forms an element with the bending beam, the bending beam being injection molded onto the slide in the area of the bearing projections formed in the other designs. This avoids additional assembly effort. The elasticity during the bending process is made possible by the fact that a section which is tapered in diameter is provided on the web arranged between the key and the bending beam, which section thus provides a further elastic bending possibility.

Eine vorteilhafte Weiterbildung der Erfindung sieht vor, daß der an der Taste angeordnete Steg in eine am Biegebalken ausgebildete Tastenaufnahme eingreift. Taste und Biegebalken bestehen somit aus zwei Teilen, wodurch die Möglichkeit geschaffen ist, die Taste unabhängig vom Federelement zu gestalten. Auch erleichtert dies die Austauschmöglichkeit der Teile, da sie unabhängig voneinander ersetzt werden können.An advantageous development of the invention provides that the web arranged on the key engages in a key receptacle formed on the bending beam. button and bending beam thus consist of two parts, which makes it possible to design the button independently of the spring element. This also makes it easier to replace the parts, since they can be replaced independently of one another.

Ebenfalls können die am Biegebalken vorgesehenen Lageransätze auch in Form von Lagerzapfen ausgebildet sein, die in am Schieber angeordneten Schwenklagern drehbeweglich einliegen.Likewise, the bearing projections provided on the bending beam can also be designed in the form of bearing journals, which lie rotatably in pivot bearings arranged on the slide.

Die Verriegelungsanordnung ist somit in mehreren Bauvarianten ausführbar, die auch miteinander kombiniert werden können.The locking arrangement can thus be implemented in several construction variants, which can also be combined with one another.

Die Erfindung wird nachfolgend anhand der Zeichnungen näher erläutert. Es zeigen:The invention is explained in more detail below with reference to the drawings. Show it:

Figur 1 einen Aufnahmebehälter für Aufzeichnungsträger mit einem in der Entnahmeposition befindlichen Schieber, räumlich dargestellt,1 shows a receptacle for recording media with a slide located in the removal position, shown spatially,

Figur 2 ein Ausführungsbeispiel der erfindungsgemäßen Verriegelungsanordnung von oben betrachtet, teilweise in geschnittener Form,FIG. 2 shows an exemplary embodiment of the locking arrangement according to the invention viewed from above, partly in a cut form,

Figur 3 die Ausführungsform des aus Figur 2 ersichtlichen Biegebalkens in Einzeldarstellung,FIG. 3 shows the embodiment of the bending beam shown in FIG. 2 in a single illustration,

Figur 4 eine weitere Ausführungsform der erfindungsgemäßen Verriegelungsanordnung mit durchgehendem Steg undFigure 4 shows another embodiment of the locking arrangement according to the invention with a continuous web and

Figur 5 eine weitere Ausführungsform der erfindungsgemäßen Verriegelungsanordnung in an den Schieber angespritzter Form.Figure 5 shows another embodiment of the locking arrangement according to the invention in molded form on the slide.

Figur 1 zeigt in räumlicher Darstellung das Gehäuse 1 eines Aufnahmebehälters für Aufzeichnungsträger wie Magnetbandkassetten, Schallplatten, Kompaktdisks oder dergleichen. In dieses sind Schieber 2 eingebracht, von denen der aus der Zeichnung ersichtliche mittige Schieber 2 in der Entnahmeposition befindlich ist. In dieser klappt der vordere Teil des Schiebers 2 nach unten und erleichtert somit die Entnahme einer darin befindlichen Kassette oder dergleichen. Die Entnahmeposition wird durch die Entriegelung des Schiebers 2 mittels einer Taste 3 am Gehäuse 1 des Aufnahmebehälters erreicht. Der im rückwärtigen Bereich einer Blende 2a gelegene Teil der Verriegelungsanordnung ist zwischen einer oberen und unteren Abdeckfläche (2b, c) angeordnet. Nach der Entriegelung wird der Schieber 2 durch eine, aus der Zeichnung nicht ersichtliche, im hinteren Bereich des Gehäuses 1 des Aufnahmebehälters befindliche Feder aus dem Gehäuse 1 herausgeschoben und in die Entnahmeposition verbracht.FIG. 1 shows the housing 1 in a spatial representation a receptacle for recording media such as magnetic tape cassettes, records, compact discs or the like. In this slide 2 are introduced, of which the central slide 2 shown in the drawing is in the removal position. In this the front part of the slide 2 folds down and thus facilitates the removal of a cassette or the like located therein. The removal position is achieved by unlocking the slide 2 by means of a button 3 on the housing 1 of the receptacle. The part of the locking arrangement located in the rear region of a panel 2a is arranged between an upper and lower cover surface (2b, c). After unlocking, the slider 2 is pushed out of the housing 1 by a spring (not shown in the drawing) located in the rear region of the housing 1 of the receptacle and brought into the removal position.

In Figur 2 ist der aus Figur 1 ersichtliche Ausschnitt der Verriegelungsanordnung im Bereich der Taste 3 in vergrößerter Form dargestellt. Im mittigen Bereich der Taste 3 ist ein Steg 4 angeordnet, der bei der aus der Zeichnung ersichtlichen Ausführungsform mit einem kreisförmigen Absatz 5 in der Tastenaufnahme 6 des Federelements 7 einliegt. Das Federelement 7 weist einen Biegebalken 8 auf, der mit zwei Lageransätzen 9a, b in am Schieber 2 angeordneten Schwenklagern 10 und 11 beweglich einliegt. Das dem Lageransatz 9a gegenüberliegende Ende des Biegebalkens 8 wird durch einen Riegel 12 gebildet, an dem eine Schrägfläche 12a vorgesehen ist. Im Bereich des Riegels 12 steht ein Kragträger 13 ab, an dessen dem Riegelfortsatz 12 gegenüberliegenden Ende der Lageransatz 9b befindlich ist. Die dargestellte Ausführungsform der erfindungsgemäßen Verriegelungsanordnung weist somit die Taste 3 mit daran befindlichem Steg 4 sowie das Federelement 7 als zwei Teile aus, die mittels des in der Tastenaufnahme 6 einliegenden Ansatzes 5 miteinander beweglich verbunden sind.FIG. 2 shows the section of the locking arrangement in the area of the button 3 shown in FIG. 1 in an enlarged form. In the central area of the key 3, a web 4 is arranged, which in the embodiment shown in the drawing lies with a circular shoulder 5 in the key receptacle 6 of the spring element 7. The spring element 7 has a bending beam 8 which, with two bearing lugs 9a, b, lies movably in pivot bearings 10 and 11 arranged on the slide 2. The end of the bending beam 8 opposite the bearing projection 9a is formed by a bolt 12 on which an inclined surface 12a is provided. In the area of the latch 12, a cantilever beam 13 protrudes, on the end of which opposite the latch extension 12 is the bearing shoulder 9b. The illustrated embodiment of the locking arrangement according to the invention thus has the button 3 with the web 4 located thereon and the spring element 7 as two parts which are movably connected to one another by means of the projection 5 lying in the key receptacle 6.

Bei der die Entriegelung des Schiebers 2 auslösenden Tastenbetätigung wird die rechtwinklig dazu stehende Entriegelungsbewegungsrichtung des Riegels 12 wie folgt umgesetzt:When the button is released to unlock the slide 2, the unlocking direction of the latch 12, which is at right angles to it, is implemented as follows:

Durch Betätigen der Taste 3 wird der auf diese wirkende Druck über den Steg 4 und den daran angeordneten Ansatz 5 auf die Tastenaufnahme 6 und somit auf den Biegebalken 8 übertragen. Die beiden Schenkel des Biegebalkens 8 werden, auf die Zeichnung bezogen, nach unten bewegt, wodurch eine Durchbiegung des Biegebalkens 8 erreicht wird. Ermöglicht wird die Durchbiegung durch die beweglich gelagerten Lageransätze 9a, b. Während des am Biegebalken 8 stattfindenden Biegevorganges beschreibt der im Bereich des Riegels befindliche Kragträger 13 eine nach innen gerichtete Schwenkbewegung, wodurch der Riegel 12 in eine mit der seitlichen Begrenzung 14 des Schiebers 2 abschließende Position verbracht wird. Der Riegel 12 gibt somit die für die Entnahmeposition des Schiebers erforderliche Ausschubbewegung frei. In der Rastposition war diese dadurch unterbunden, daß der Riegel 12 in einer Öffnung des aus der Figur 1 ersichtlichen Gehäuses 1 des Aufnahmebehälters eingriff und somit den Schieber 2 im Gehäuse 1 verriegelte. Bei Rückführung der Taste in ihre Ruhebewegung wird schließlich der Riegel 12 wieder nach außen bewegt und in dessen Ruheposition verbracht.By pressing the button 3, the pressure acting thereon is transmitted via the web 4 and the attachment 5 arranged thereon to the button holder 6 and thus to the bending beam 8. The two legs of the bending beam 8 are, based on the drawing, moved downwards, whereby a bending of the bending beam 8 is achieved. The deflection is made possible by the movably mounted bearing lugs 9a, b. During the bending process taking place on the bending beam 8, the cantilever beam 13 located in the area of the bar describes an inward pivoting movement, as a result of which the bar 12 is brought into a position that closes with the lateral boundary 14 of the slide 2. The latch 12 thus releases the extension movement required for the removal position of the slide. In the latching position, this was prevented by the latch 12 engaging in an opening in the housing 1 of the receptacle shown in FIG. 1 and thus locking the slide 2 in the housing 1. When the key is returned to its rest movement, the latch 12 is finally moved outward again and brought into its rest position.

Wird nun der Schieber 2 wieder in das Gehäuse 1 des Aufnahmebehälters zurückgeführt, ermöglicht die am Riegel 12 angeordnete Schrägfläche 12a eine durch den Wandbereich der Gehäuseöffnung des Gehäuses 1 ausgelöste Rückführung des Riegels 12 auf die seitliche Begrenzung 14 des Schiebers 2. Sobald der Schieber 2 im Gehäuse 1 in seine Endposition verbracht ist, gleitet der Riegel 12 wiederum in die am Gehäuse 1 befindliche Öffnung ein und verriegelt somit den Schieber 2 im Gehäuse 1 des Aufnahmebehälters.If the slider 2 is now returned to the housing 1 of the receptacle, the inclined surface 12a arranged on the latch 12 enables the latch 12 to be returned to the lateral boundary 14 of the slider 2, triggered by the wall area of the housing opening of the housing 1 Housing 1 is brought into its end position, the latch 12 in turn slides into the opening in the housing 1 and thus locks the slide 2 in the housing 1 of the receptacle.

Die in Figur 3 gezeigte Einzeldarstellung des bereits aus Figur 2 ersichtlichen Federelements 7 zeigt den Biegebalken 8 mit daran befindlichen Lageransätzen 9a, b. Diese bestehen bei der erfindungsgemäßen Ausführungsform aus Lagerzapfen, die in entsprechenden Aussparungen der aus Figur 2 ersichtlichen Schwenklager 10 und 11 einliegen. Der am Biegebalken 8 im Bereich des Riegels 12 abzweigende Kragträger 13 ermöglicht die elastische Beweglichkeit des Riegels 12 und bewirkt durch dessen Bewegungsrichtung die Lage des Riegels in der Ent- oder Verriegelungsposition. Im Falle eines über die Tastenaufnahme 6, die mit Klauen 6a versehen ist, auf den Biegebalken 8 ausgeübten Druckes wird dieser durchgebogen, wobei der Kragträger 13, auf die Zeichnung bezogen, eine Schwenkbewegung nach rechts beschreibt und somit der Riegel 12 nach oben bewegt wird. Sobald die Schrägfläche 12a mit der seitlichen Begrenzung 14 des Schiebers 2 abschließt befindet sich die Verriegelungsanordnung in der Entriegelungsposition, die einen Ausschub des Schiebers 2 ermöglicht. Bei Druckentlastung wird aufgrund der am Biegebalken 8 auftretenden Entspannung sowie der nach außen gerichteten Schwenkbewegung des Kragträgers der Riegel 12 wieder ausgeschwenkt und befindet sich somit in seiner Ruhestellung.The individual representation shown in FIG. 3 of the spring element 7 that can already be seen in FIG. 2 shows the bending beam 8 with bearing projections 9a, b located thereon. In the embodiment according to the invention, these consist of bearing journals which lie in corresponding recesses in the pivot bearings 10 and 11 shown in FIG. The cantilever 13 which branches off on the bending beam 8 in the region of the bar 12 enables the bar 12 to be moved flexibly and, by means of its direction of movement, causes the bar to be in the unlocked or locked position. In the case of a pressure exerted on the bending beam 8 via the key receptacle 6, which is provided with claws 6a, the latter is deflected, the cantilever beam 13, based on the drawing, describing a pivoting movement to the right and thus the bolt 12 being moved upward. As soon as the inclined surface 12a ends with the lateral boundary 14 of the slide 2, the locking arrangement is in the unlocked position, which enables the slide 2 to be pushed out. When the pressure is released, the bolt 12 is pivoted out again due to the relaxation occurring on the bending beam 8 and the outward pivoting movement of the cantilever and is thus in its rest position.

Die in Figur 4 dargestellte Ausführungsform der erfindungsgemäßen Verriegelungsanordnung zeigt die Taste 3, die über einen durchgehenden Steg 15 mit dem Biegebalken 8 in Verbindung steht. Am Steg 15 ist ein im Durchmesser verjüngter Abschnitt 16 vorgesehen, wodurch ebenfalls ein elastischer Biegevorgang während der Entriegelung des Schiebers gewährleistet ist.The embodiment of the locking arrangement according to the invention shown in FIG. 4 shows the button 3, which is connected to the bending beam 8 via a continuous web 15. A section 16 tapered in diameter is provided on the web 15, which likewise results in an elastic bending process during the unlocking the slider is guaranteed.

Aus Figur 5 ist eine Ausführungsform der erfindungsgemäßen Verriegelungsanordnung ersichtlich, bei der das Federelement 7 am Gehäuse des Schiebers 2 angespritzt ist. Da auch bei dieser Ausführungsform der Biegebalken 8 sowie der Kragträger 13 federelastisch ausgebildet sind, kann mittels auf die Tastenaufnahme 6 ausgeübten Drucks eine Durchbiegung des Federelements 7 erzielt werden, wodurch der Riegel 12 in eine Entriegelungsposition verbracht werden kann.5 shows an embodiment of the locking arrangement according to the invention, in which the spring element 7 is injection molded onto the housing of the slide 2. Since the bending beam 8 and the cantilever 13 are also designed to be resilient in this embodiment, the spring element 7 can be deflected by means of pressure exerted on the key receptacle 6, as a result of which the bolt 12 can be brought into an unlocking position.
